What is irrational number

Hence 'pi' is an irrational number. We can have infinitely many irrational numbers between root 2 and root 3. A few examples of irrational numbers between root 2 and root 3 are 1.

Yes, irrational numbers are non-terminating and non-recurring. Terminating numbers are those decimals that end after a specific number of decimal places. For example, 1. Whereas non-terminating and non-recurring numbers are considered as the never-ending decimal expansion of irrational numbers.

A surd refers to an expression that includes a square root, cube root, or other root symbols. Surds are used to write irrational numbers precisely. All surds are considered to be irrational numbers but all irrational numbers can't be considered surds. Learn Practice Download.
